The pups. Lucille (at least the 2016s) has 490 R/T pups. I thought at first that Gibson cheaped out on the pups. Until I played it. Then I understood. They work really good. Yes, of course for bluesy music. But the best kept secret about them is that they are volume and gain monsters. Turn up the volume and peg the gain, and off you go! Virtually no different for feedback than an LP. I believe the Lucille is probably closer to a good LP than any other ES model. Yes, including ES-LPs. Has a fine tuning bridge too.We all know that the Lucille ES355 has no f holes to reduce feedback, and I've read that BB asked for a slightly slimmer neck (width not depth) are there any other differences between Lucille and the typical ES355 ?
